Aerosol-based processes for the production of battery materials

With the introduction of the lithium battery by Sony in 1990, the development of active materials has gone through a steady process with the aim of increasing energy density. This is realised through the development of novel, nickel-rich and cobalt-free cathode materials, the production of silicon-carbon composite materials and the development of solid-state batteries. The increasing demand for applications within electromobility or stationary energy storage requires the implementation of novel, sustainable and continuous manufacturing processes as well as processes for coating active materials. Aerosol-based methods based on spray drying / spray calcination and spray granulation are presented using selected examples. First results on electrochemical characterisation are shown.
